HAY-STACKER D-RUM.

'SPECIFICATION forming part of Letters :Patent No. 721,616, dated February 24, 1903.- Application filed November 14, 1902. VSerial Ne. 131,404. (No model.)

To all whom t mag/concern.-

Be it known that I, PHILErUs E. SNEER, a citizen of the United States, and a resident of Ellensbnrg,in the county of Kittitas and State of Washington, have made certain new and useful Improvements in Hay-Stacker Drums, of which the following is a speciiication.

My invention is an improvement in drums,- and especially in drums designed for use on hay-stackers, and has for an object, among others, to provide a novel construction where-A by to increase the motion of the fork without increasing the speedot the horse or other power, also to furnish the greatest amount of power when most needed and the greatest speed when most needed; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1' is aperspective view of a hay-stacker provided with' my invention, and Fig. 2-is a vertical cross-section through the drum on about line 2V 2 of Fig. l.

The stacker may in general respects be of ordinary construction,having a suitablef ram until the fork reaches the point where it discharges the hay on the stack. It is thereforey desirable to provide for the maximum power for starting the fork on its upward movement and for the maximum speed as the fork Y approaches its uppermost'or perpendicular position. It is also desirable to accomplish this without varying the speed of the horse or other power, and I accomplish the desired results in a simple manner by means of the drum A, formed with two sections A and A2, which may be of `,equal diameter, arranged side by side andconcentric, are separated by the intermediate ange a, and are provided at their ends with the iianges a and a2, spaced apart from the intermediate flange a distance equal to the diameter of therope, so that the ropes wound on one drum and off the other will operate to automatically increase and decrease the diameter of this drum-section to the extent of twice the diameter of the rope for each round thereof on the dru m-section. Further, by winding one rope on one drum as the other rope is wound oft the other the variation between the two drums is accordingly increased. The rope D connects at one end with the fork, passes thence over a guid e-pulley D', and is secured to and wound on the section A' of the drum A, while the other rope E is securedto'and wound on the section'A2 of thedrum and extends thence and is connected. with the horse or other power. When the fork is down, the rope D is unwound from its drum-section A'and the rope E is wound on its drum-section A2, so the drum-section A2, havingithe rope E, is of Vits greatest diameter, and the drum-section A', receiving' the `rope D, is of its least diameter whenV the fork is down. It will thusbe noticed thatithe diameterof the drums is increased and decreased by the winding up, and unwinding of the ,ropesjand that when the fork is down the drum-section receiving lthe rope E, isof its greatest. diameter, and consequently the power has its greatest leveragein starting the fork on its upward movement. As the fork approaches its upright position the, rope D,'having been wound on its drum-section A', will have increased the diameter of such drum-section and the speed of the drum will increase as such fork approaches its upright position. v

Having thus described my'invention, what Iclaim as new, and desire to secure byLetters Patent, is

l. .The combination of the framing the stacking-fork pivoted thereto, the drum having adjacent drum-sections and flanges on said drum-sections and spaced apart a distance corresponding to the diameter of the ropes, the rope connected with one drum-section and extending thence and connectedA with the fork, and the power-rope connected with the other drum-section. substantially as set forth.

2. The combination with the stacker-trame and stacking-fork of a drum having sections provided with lian ges spaced apart a distance IOU 1o pivoted fork combined with the fork-lifting y rope and the power-rope and a drum having sections to which said ropes are secured, the diameters of the drum-sections being increased and decreased by the unwinding and winding of the ropes thereon in single super 15 posed coils substantially as set forth.
